Model 348 Universal Voltage Regulator

Replaces Delco H3500 and Basler KR4

Size: 2 1/2" x 3 7/8" x 2" Tall
Mounting Centers: 2 3/8" x 3 1/2"

The Model 348 is normally connected with only 4 wires. It comes factory setwith a short form (B to A) terminals and the dip switches set for 208 – 240volts 60 Hertz use. 1 OFF – 2 ON – 3 ON. In this configuration it works inalmost all modern 12 wire generator sets from 190 to 277 volts and with exciterfields from 9 to 100 Ohms.

With the power and sensing input voltage connected together to terminals C& BA, and output terminals connected to terminals F+ and F-, it can work inalmost any voltage configuration.

This AVR is "Universal" because it can also work with any 4 wire generator,at any voltage and Hertz, just by programming 3 simple dip switches located onthe AVR. As long as you feed power to input terminals C&B with 100 to 300volts and then connect sensing terminals C&A to the generator outputvoltage, you can make it work on almost any configuration.
